Molar and molecular weight of Hg2Cl2

• Molecular formula: Hg2Cl2 or Cl2Hg2
• Relative molecular weight of Hg2Cl2: 472.086
• Molar mass of Hg2Cl2: 472.086 g/mol (0.47209 kg/mol)

Calculation of the relative molecular and molar mass of Hg2Cl2

• Mr[Hg2Cl2] = Ar[Cl] * 2 + Ar[Hg] * 2 = 35.453 * 2 + 200.59 * 2 = 472.086
• Molar mass (kg/mol) = Mr[Hg2Cl2] : 1000 = 472.086 : 1000 = 0.47209 kg/mol

Hg2Cl2: percent composition by element

• Chlorine (Cl) = 70.906 : 472.086 * 100 = 15.02 %
• Mercury (Hg) = 401.18 : 472.086 * 100 = 84.98 %
